The rules for a reroof in Mifflinburg
Layers
Two layers means a tear-off
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). With 71% of Mifflinburg’s homes were built before 1980, ask what is under the newest layer.
Ice barrier
Set by the local climate table
Whether an eave membrane is a code item depends on the climate table the municipality filled in when it adopted the code (IRC R905.1.2, Table R301.2). Ask the borough code office or the contractor what Mifflinburg’s says.
